How to increase the volume on the Xiaomi Redmi phone: from standard settings to hidden features

Xiaomi Redmi smartphone owners often face the problem of not having enough loud sound — whether it’s listening to music, watching videos or talking on the phone. The manufacturer deliberately limits the maximum volume in the MIUI firmware to protect speakers from overload and extend their lifespan. However, these restrictions do not always suit users, especially in noisy conditions or when using the phone as a multimedia center.

In this article, we’ll look at all the possible ways to turn up the volume on Xiaomi Redmi, from basic system settings to hidden engineering menu features and third-party apps. It’s important to understand that some methods can affect sound quality or even reduce the life of speakers, so we’ll point out all the risks and give recommendations for safe use. If you’re willing to experiment, let’s go!

1. Standard volume settings in MIUI

Before resorting to radical measures, check the basic sound settings in your Redmi. MIUI It offers a few built-in volume adjustment tools that many users overlook.

Open the Settings → Sound and Vibration menu. Here you will find volume sliders: ringing melodies, notifications, media and alarm clocks. Make sure they are all set to maximum. Pay attention to the Adaptive Sound option, which automatically adjusts the volume to ambient noise, but sometimes it works incorrectly, lowering the sound instead of amplifying it.

• 🔊 Separate adjustment: B MIUI 12+ Call volume and media are set separately.
• 🎵 Equator: Enable the built-in equalizer in Settings → Sound. → Equalizer and select Basa or Rock preset – this can subjectively increase volume by amplifying low frequencies.
• 📱 Do Not Disturb Mode: Make sure it is turned off – sometimes users accidentally activate it, which leads to lower notification volume.

If you're still too quiet after this manipulation, move on to the next section, but first check if the problem is hardware, like clogging the speaker or damage to the plume, and then compare the volume when played through the speaker and headphones.

2. Engineering menu: hidden sound settings

MIUI hides from the user the advanced audio settings available through the engineering menu, a method that bypasses software volume limits, but requires caution – incorrect changes can cause the speakers to crash or damage.

To open the engineering menu, enter the phone combination in the application:

##36446337##

After that, you will be taken to the Engineering Mode menu, go to the Hardware Testing → Audio section, and you will be interested in the following options:

• 🔧 Max Vol – maximum volume for different types of sound (calls, multimedia, headphones).
• 📊 Normal Mode – Standard Mode where you can increase the values to 160 (default 128-140).
• 🔇 Headset Mode – Headphone settings (beware of raising above 150 to avoid damaging the membranes).

Warning: Changes above 150-160 can cause sound distortion and overheating of the speakers, and we recommend increasing the volume in stages, checking the sound quality after each change.

Write down the initial values of the parameters|Increase the volume by no more than 10 units at a time|Check the sound after each change.|Do not change the settings in the "Mic" and "Receiver" sections)-->

3. Apps to amplify sound: top-5 utility

If standard methods don't work, you can use third-party applications, which work on two principles: either amplify sound at the software level (with the risk of distortion), or optimize the frequency range for subjective volume increase.

We tested dozens of utilities and selected the 5 most effective for Xiaomi Redmi:

• 🎛️ Volume Booster GOODEV — A simple booster with presets for music, video and games, which allows you to increase the volume to 200% of the standard, but in practice, values above 130% give a strong distortion.
• 🎧 Equalizer FX — powerful equalizer with bass amplification and high frequencies, suitable for improving the sound in headphones.
• 🔊 Precise Volume – allows precise volume settings in 1% increments, which is useful for fine tuning.
• 🎵 Music Volume EQ — combines equalizer and booster, supports presets for different genres of music.
• 📱 Volume Unlocker (Root) is the most powerful solution, but requires root rights. MIUI system-level.

Important: When using boosters, monitor the temperature of the phone – amplifying the sound increases the load on the processor. Also pay attention to battery discharge: some applications (for example, Equalizer FX) run in the background and can reduce battery life by 10-15%.

💡

Before installing the booster, check its compatibility with your version of MIUI. Some applications (such as Volume Unlocker) require unlocking the bootloader and may result in a loss of warranty.

4. Adjust audio via ADB (for advanced users)

If you're not afraid of the command line, you can turn up the volume through ADB (Android Debug Bridge), which doesn't require root rights, but requires a computer and basic terminal skills, and the advantage of the method is that the changes take effect at the system level, without having to keep the background processes.

To start, enable USB debugging on your phone: Settings → About Phone → MIUI version (click 7 times to activate Developer Mode), then go back to Settings → Additional → For Developers and enable USB Debugging.

Connect your phone to your PC, open the terminal (or PowerShell on Windows), and type in commands:

adb shell settings put global volume_steps 30


adb shell settings put global volume_music_steps 30




adb shell settings put global volume_voice_steps 15

These commands increase the number of volume control steps, which allows you to adjust the sound more accurately. To directly increase the maximum volume, use:

adb shell settings put global volume_music_max_index 15


adb shell settings put global volume_system_max_index 7

Critical Information: Do not set a value volume_music_max_index higher 15 — This can cause hardware damage to the speaker. 10/11 safe-maximum — 12-13.

5. Hardware causes of silent sound and their elimination

If the software methods don’t work, the problem may lie in the hardware, and the most common quiet sound on Xiaomi Redmi is caused by the following reasons:

• 🧹 Clogging speaker - dust and pile accumulate in the grille, blocking sound waves. Clean the hole with a soft brush or compressed air (do not use sharp objects!).
• 🔌 The speaker plume is damaged, which is common in phones after falling or disassembling, and the sound disappears when you press the body or change the position of the phone.
• 🔋 Weak battery – when the charge is low (less than 15%), the system automatically lowers the volume to save energy.
• 🔊 The malfunction of the amplifier chip requires a diagnosis at the service center, symptoms: the sound is distorted or completely absent, even in headphones.

To check the speaker, use the hardware component test. Enter the combination in the Phone application:

##4636##

Select Equipment Test → Audio and check playback on all channels. If sound is missing on one of the speakers (e.g., top or bottom), this indicates a hardware malfunction.

⚠️ Warning: Don't try to disassemble the phone yourself to clean the speaker unless you have experience. - Redmi Note models 10/11 speaker is glued to the body, and careless actions can damage the plume or membrane.

6. Alternative ways to amplify sound

If all of the above methods fail, consider alternative solutions:

• 🎧 Using an external amplifier, such as Bluetooth speakers or portable speakers, even budget models (such as the Xiaomi Mi Portable Speaker) sound louder than the built-in speaker.
• 🔗 Bluetooth 5.0 connectivity – modern headphones (e.g. Redmi Buds 4) support aptX and LC3, which improve the sound quality compared to wired.
• 📱 Flashing to custom firmware – for example, LineageOS or Pixel Experience do not have strict volume limits, but require unlocking the bootloader and can deprive you of warranties.
• 🔧 Replacement of the speaker – if your Redmi is older 2-3 The cost of replacing the speaker at the service center could be worn out: 800-1500 RUB (depending on the model).

For the Redmi K40/K50 stereo models, check the sound balance between the top and bottom speakers. Sometimes one of them is quieter due to incorrect settings in MIUI. You can fix this through the engineering menu (section Audio → Speaker Balance).

💡

The safest way to increase volume is to use an equalizer and external devices (columns, headphones), methods that change system files or engineering menus should be used only when you are confident in your actions.

7. Frequent mistakes and how to avoid them

When trying to turn up the volume, users often make mistakes that lead to the opposite result or damage to the phone.

• 🔊 Resetting the sound settings - after the update MIUI Some settings are reset. Always check the settings after the update.
• 📱 Ignoring updates in new versions MIUI They often fix sound bugs. MIUI 14 fixes quiet sound problem in Redmi Note 11 when connected via Bluetooth.
• 🔧 Incorrect calibration in the engineering menu – changing the Mic Gain settings instead of Speaker Gain leads to noise during calls.
• 🎵 Using pirated boosters – applications from unverified sources may contain malicious code or damage system files.

Another common mistake is trying to increase the volume through files. mixer_paths.xml. This method requires root rights and editing system files, which can lead to a phone breeze (complete inoperability). If you are not a seasoned user, it is best to avoid such experiments.

⚠️ Attention: On Redmi models 9A/9C single-core speaker, volume increase higher 140 The engineering menu is distorted by 2-3 For these phones, we recommend limiting the value to the 130-135.
